The order of the steps is:

Step 1. is the fifth statement

Step 2. is the first statement

Step 3. is the second statement

Step 4. is the third statement

Step 5. is the fourth statement

Step-by-step explanation:

Lets revise the steps of construct the bisector of ∠ A

Steps:

1. Place the point of the compass on point A and draw an arc that

intersects the sides of ∠A

Label the points of intersection as points B and C

2. Place the point of the compass on point B and draw an arc in the

interior of the angle

3. Without changing the opening of the compass place the point of

the compass on point C and draw another arc in the interior of the

angle

4. Label the intersection of the arcs in the interior of the angle as

Point D

5. Use the straightedge to draw AD ray

From the steps above

The order of the steps is:

Step 1. is the fifth statement

Step 2. is the first statement

Step 3. is the second statement

Step 4. is the third statement

Step 5. is the fourth statement

$\bf S(t)=4\pi \left( \cfrac{3}{8}t^4 \right)^2\impliedby \textit{distributing the exponent}
\\\\\\
S(t)=4\pi \left( \cfrac{3^2}{8^2}t^{4\cdot 2} \right)\implies S(t)=4\pi \cdot \cfrac{9t^8}{64}\implies S(t)=\cfrac{4}{64}\cdot \cfrac{9\pi t^8}{1}
\\\\\\
S(t)=\cfrac{1}{16}\cdot \cfrac{9\pi t^8}{1}\implies S(t)=\cfrac{9\pi t^8}{16}$

Ten pairs of data yield r = 0.003 and the regression equation =2+3x Also, the mean = 5 What is the best predicted value of y for

Olenka [21]

Answer:

$\hat y(2)=2 +3(2) =8$

C 8.0

Step-by-step explanation:

Assuming the linear model y=mx+b where m is the slope and b the intercept.

For this case the slope with the following formula:

$m=\frac{S_{xy}}{S_{xx}}$

Where:

$S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}$

$S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}$

$b=\bar y -m \bar x$

After the calculations we see that m=3 and b=2 from the info given by the linear model.

For this case we have the equation obtained by least squares given by:

$\hat y =2 +3x$

Where 2 represent the intercept and 3 the slope. We are interested on the best predicted value of y when x=2.

If we see our linear model we have the equation in terms of y and x. So we can replace directly the value of x=2 into the equation and see what we got:

$\hat y(2)=2 +3(2) =8$
